so residual at x = -2 is
0 - 2 = -2
Answer:cost of a friends meal in terms of a is 35/a and cost of each friends meal when the nunber if friends is 5 is $7
Step-by-step explanation:
The cross-section cut by the plane yields a quadrilateral with length and width equal to the length and width of the face that is parallel to the plane.
At max a rotation can be equal to π or 180°
So if it's rotated 110° counterclockwise then it's equal to rotation of supplementary angle clockwise
Supplementary angle=180-110=70°
70° rotation clockwise
(2/3) / 3 = 1/x...2/3 to 3 lawns = 1 to x lawns
cross multiply
(2/3)(x) = (3)(1)
2/3x = 3
x = 3 * 3/2
x = 9/2 or 4 1/2 lawns can be cut with a full tank of gas
